Swansea have expressed an interest in both players, although Ayew’s wages would be a big stumbling block to his return to the Liberty Stadium.
But the Hammers want £15m for Sakho and hope to sell him to a French club instead of a relegation rival, with Rennes and Strasbourg interested.
Asked about Swansea’s interest in the striker, boss David Moyes said: “At the moment I’m not mad keen to strengthen anybody else.
“I’m not in a hurry to sell. I’d like to add. We’ve not got a massive squad. If it was making me better it might be different.”
